[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0028] Combined with Figures 1 to 2 , the embodiment of the present application provides a cooking device 1. The cooking device 1 provided in the embodiment of the present application may be a microwave oven, an oven or a steam box. The cooking device 1 provided in the embodiment of the present application may also be an integrated machine integrating any two functions among the three functions of microwave, steam or baking. The cooking device 1 provided in the embodiment of the present application may also be a microwave steam baking integrated machine. The cooking device 1 includes a device main body 10, an air outlet assembly 20 and an air outlet cover 30.

[0029] Specifically, the device main body 10 can install and carry various components. According to the different types of the cooking device 1, the device main body 10 can carry a microwave component, a steam component, a heating component, etc. The device main body 10 has a cooking cavity 101. The cooking cavity 101 can be used to place food ingredients and can accommodate microwave, steam or hot air to heat the food ingredients therein. Optionally, both ends of the device main body 10 have openings respectively communicating with the cooking cavity 101. The opening on one side of the device main body 10 can be correspondingly used for installing a door body (not shown in the figure), and the door body can open or close the opening, allowing the user to put or take out food ingredients into or from the cooking cavity 101 through the opening. The opening on the other side of the device main body 10 can be correspondingly used for installing an air outlet hood 30 and an air outlet component 20. The air outlet hood 30 and the air outlet component 20 can cooperate to generate an air flow in the cooking cavity 101 to achieve uniform heating of the food ingredients.

[0030] In some embodiments, a sunken part 11 is provided on one side of the device main body 10 facing the cooking cavity 101. The sunken part 11 can be used for installing components such as a microwave component, a steam component or a heating component. The setting of the sunken part 11 enables the sizes of components such as a microwave component, a steam component or a heating component to be partially accommodated by the cooking cavity 101, thereby reducing the overall occupied space of the cooking device 1.

[0031] Combined with Figure 2 , the air outlet component 20 is installed on the device main body 10. The air outlet component 20 can blow air into the cooking cavity 101 through the air outlet hood 30. The air outlet component 20 includes a fixed cover, a bracket, a driving device and air outlet blades. The driving device can be fixed on the fixed cover through the bracket. The air outlet blades are drivingly connected to the driving device. The air outlet blades can generate an air flow by rotating. The air flow generated by the air outlet blades can be guided to the cooking cavity 101 through the air outlet hood 30.

[0032] The air outlet hood 30 is installed on the device main body 10 and communicates with the cooking cavity 101. The air outlet hood 30 is installed at one end of the device main body 10 having an opening. The air outlet hood 30 is provided with an air outlet 321, and the air flow generated by the air outlet component 20 can enter the cooking cavity 101 from the air outlet 321. The air outlet hood 30 can rectify and guide the air flow formed by the air outlet component 20, and then introduce the air flow into the cooking cavity 101. The air outlet hood 30 can also form an air return opening 311 corresponding to the air outlet component 20, and the air flow in the cooking cavity 101 can flow back to the air outlet blades from the air return opening 311. Through the above method, an air flow circulation can be formed in the cooking cavity 101, thereby promoting the flow of heat in the cooking cavity 101 to improve the uniformity of heating the food ingredients inside the cooking cavity 101.

[0033] In some embodiments, combined with Figure 2, the device main body 10, the air outlet cover 30, and the air outlet assembly 20 are separately arranged. The device main body 10 can be used to install the air outlet cover 30 and the air outlet assembly 20. The air outlet assembly 20 can drive the air flow convection through the rotation of the air outlet blades. The air outlet cover 30 can integrate and guide the air flow so as to input it into the cooking cavity 101 in a desired manner. By setting the device main body 10, the air outlet cover 30, and the air outlet assembly 20 separately, during the assembly process, different air outlet covers 30 and air outlet assemblies 20 can be selected and matched for the device main body 10. By selecting and matching different air outlet covers 30 and air outlet assemblies 20, cooking devices 1 with different configurations can be assembled.

[0034] In some embodiments, there are multiple air outlet covers 30 and multiple air outlet assemblies 20. The air outlet cover 30 can include an air outlet cover 30 with a single air return port 311 or an air outlet cover 30 with multiple air return ports 311. The air outlet cover 30 can also include an air outlet cover 30 with different-shaped air outlet ports 321. The air outlet assembly 20 can include a single fan assembly or a double fan assembly, etc. Among them, the device main body 10 is a general cavity. The device main body 10 has the same assembly method with different air outlet covers 30. The device main body 10 also has the same assembly method with different air outlet assemblies 20. In this way, the cooking device 1 can be equipped with different-configured air outlet covers 30 and air outlet assemblies 20. For example, during the assembly process, according to different required configurations, a double-fan air outlet assembly 20 and an air outlet cover 30 with double air return ports 311 can be installed on the device main body 10; or a single-fan air outlet assembly 20 and an air outlet cover 30 with a single air return port 311 can be installed.

[0035] In the related art, a sunken part 11 is arranged on one side of the device main body 10 facing the cooking cavity 101. The sunken part 11 can be used for installing components such as a microwave component, a steam component, or a heating component. The setting of the sunken part 11 will hinder the air outlet of the air outlet cover 30, resulting in a decrease in the uniformity of the air flow in the cooking cavity 101. To improve the above technical problems, the following embodiments can be provided in this application.

[0036] It should be noted that the embodiments provided in this application also have the technical effect of improving the air flow uniformity without setting the sunken part 11. This application has carried out targeted design for the case with the sunken part 11. Compared with the solutions in the related art, the embodiments of this application have a better air flow uniformity improvement effect for the case with the sunken part 11.

[0037] Refer to Figures 3 to 11For illustration purposes, an embodiment of the present application provides an air outlet hood 30. The air outlet hood 30 includes a main board body 31 and side board bodies 32. The main board body 31 is provided with an air return opening 311. The side board bodies 32 are disposed on at least one side of the main board body 31 and are connected to the main board body 31. Among them, the side board bodies 32 are provided with air outlet openings 321. Through the air outlet openings 321 of the side board bodies 32, the airflow generated by the air outlet blades of the cooking device 1 can be introduced into the cooking cavity 101, and through the air return opening 311 of the main board body 31, the airflow in the cooking cavity 101 can flow back from the air return opening 311 to the air outlet blades. In this way, an air flow circulation can be formed in the cooking cavity 101.

[0038] For convenience of description, the main board body 31 has different first reference directions (as shown by the X direction in the figure) and second reference directions (as shown by the Y direction in the figure). At least one side of the main board body 31 in the second reference direction is configured to be correspondingly arranged with the side of the device main body 10 provided with the sunken part 11. Optionally, the first reference direction is the length direction of the main board body 31, and the second reference direction is the width direction of the main board body 31. Optionally, the first reference direction and the second reference direction are perpendicular. Optionally, when the cooking device 1 is in use, the second reference direction is parallel to the gravity direction.

[0039] Combined with Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 9 , in this embodiment, the side board body 32 is disposed on the adjacent side of the side of the main board body 31 corresponding to the sunken part 11. In this way, the side board body 32 provided with the air outlet opening 321 can bypass the obstruction of the sunken part 11, so that the airflow of the air outlet opening 321 can smoothly blow out into the cooking cavity 101, thereby promoting the flow of the airflow in the cooking cavity 101 and improving the uniformity of the airflow.

[0040] The air outlet opening 321 has a length direction and a width direction, and the length direction of the air outlet opening 321 is inclined relative to the first reference direction. In other words, the length direction of the air outlet opening 321 is set at an angle with the first reference direction. Through the inclination of the air outlet opening 321, in the direction away from the main board body 31, the air outlet position of the airflow will gradually move away from one side of the main board body 31, thereby reducing the influence of the corresponding components on that side on the air outlet.

[0041] Specifically, the length direction of the air outlet 321 inclines to one side of the second reference direction in the direction away from the main board body 31. Specifically, one end of the air outlet 321 close to the main board body 31 is closer to the sunken part 11 than the end of the air outlet 321 away from the main board body 31. In the cooking device 1, the length direction of the air outlet 321 inclines to the side away from the sunken part 11 in the direction away from the main board body 31. In this way, the position of the air outlet can gradually move away from the sunken part 11 in the direction away from the main board body 31, thereby reducing the blockage of the sunken part 11 to the air flow.

[0042] Furthermore, the air flow direction generated during the rotation of the air outlet blades is not perpendicular to the extension direction (the second reference direction) of the side board body 32. The air flow direction generated by the air outlet blades will blow obliquely towards the side board body 32 at a certain angle. By obliquely setting the length direction of the air outlet 321, the direction of the air outlet 321 can be matched with the air flow direction generated by the air outlet blades, so as to more conveniently direct the air flow into the cooking cavity 101.

[0043] In some embodiments, combined with Figure 8 , the side board body 32 has an air outlet area. The air outlet area can be the entire side board body 32, or the air outlet area can be an area formed by sheet metal working or bending of the side board body 32 for opening the air outlet 321, and no specific limitation is made here. Optionally, the air outlet area can also be an area formed by the air outlet 321 at one end of the side board body 32 extending to the air outlet 321 at the other end.

[0044] Combined with Figure 8 , a plurality of air outlets 321 are arranged at intervals in the air outlet area. The angle of inclination of the air outlet 321 with respect to the first reference direction is ∠A, and the angle between the line connecting the geometric centers of the air outlet area and the air return port 311 and the first reference direction is ∠D. The angle between the line connecting the geometric centers of the air outlet area and the air return port 311 and the tangent line of the outer edge of the air return port 311 is ∠C. The above parameters satisfy .

[0045] Specifically, ∠C and ∠D can be calculated by trigonometric functions based on each dimension. For example, the distance between the projections of the geometric centers of the air outlet area and the air return port 311 in the second reference direction is H, the distance between the projections of the geometric centers of the air outlet area and the air return port 311 in the first reference direction is L, and the radius of the air return port 311 is r. In this case, the above parameters satisfy In the above manner, the tilt angle of the air outlet 321 can be matched with the position of the air return port 311. Since the air return port 311 is correspondingly arranged with the air outlet blades, in the above manner, the tilt angle of the air outlet 321 can be matched with the position of the air outlet blades, so that the air outlet 321 can more effectively blow the air flow generated by the air outlet blades into the cooking cavity 101.

[0046] In some embodiments, a plurality of air outlets 321 are provided on the side plate body 32, and the plurality of air outlets 321 are arranged at intervals in the second reference direction, and the length directions of the plurality of air outlets 321 are parallel to each other.

[0047] In some embodiments, the main board body 31 has opposite front and rear sides in its thickness direction. In the direction away from the main board body 31, the side plate body 32 is inclined backward from the outer edge of the main board body 31. A flow guide plate 322 is provided on at least one side in the width direction of the air outlet 321, and the flow guide plate 322 extends obliquely forward from the side plate body 32. The flow guide plate 322 can guide the air flow blown out from the air outlet 321. By providing the flow guide plate 322, the air flow direction of the air outlet 321 can be made closer to the front side of the main board body 31. In other words, the flow guide plate 322 can cooperate with the air outlet 321 to change the direction of the air flow to improve the uniformity of the air flow inside the cooking cavity 101.

[0048] Furthermore, the rotation direction of the air outlet blades has a tangential direction at a position close to the side plate body 32. In the tangential direction, the air outlet 321 has a first side and a second side in sequence, and the flow guide plate 322 is provided at least on the second side in the tangential direction. In this way, the setting of the flow guide plate 322 can be matched with the rotation direction of the air outlet blades, so as to effectively guide the air flow to the cooking cavity 101.

[0049] It should be noted that the air flow direction generated by the rotation of the air outlet blades is not perpendicular to the extension direction of the side plate body 32. And the air flow direction generated by the air outlet blades is related to the rotation direction of the air outlet blades. Combining Figures 3 to 7 The situation where the flow guide plate 322 is provided only on one side of the air outlet 321 can be seen in the following description.

[0050] Refer to Figure 3 In the case where the air outlet blades rotate counterclockwise, for the left side plate body 32, the air flow direction is left downward. The rotation direction of the air outlet blades has a downward tangential direction at a position close to the side plate body 32. The flow guide plate 322 needs to be provided on the lower side of the air outlet 321 to effectively guide the air flow to the cooking cavity 101. That is, in the downward tangential direction, the upper side of the air outlet 321 is the first side, and the lower side of the air outlet 321 is the second side.

[0051] Combining Figure 3, when the air outlet blade rotates counterclockwise, for the right side plate body 32, the air flow direction is upward to the right. The rotation direction of the air outlet blade is upward in the tangential direction near the side plate body 32. The flow guide plate 322 needs to be arranged on the upper side of the air outlet 321 to effectively guide the air flow to the cooking cavity 101. That is, in the upward tangential direction, the lower side of the air outlet 321 is the first side, and the upper side of the air outlet 321 is the second side.

[0052] Combined with Figure 4 , for example, when the air outlet blades corresponding to the left air return opening 311 rotate clockwise and the air outlet blades corresponding to the right air return opening 311 rotate counterclockwise, for the left side plate body 32, the air flow direction is upward to the left, and for the right side plate body 32, the air flow direction is upward to the right. Therefore, the rotation direction of the air outlet blade is upward in the tangential direction near both side plate bodies 32. That is, for both side plate bodies 32, it satisfies that in the upward tangential direction, the lower side of the air outlet 321 is the first side, and the upper side of the air outlet 321 is the second side.

[0053] Combined with Figure 6 , for example, when the air outlet blades corresponding to the two air return openings 311 both rotate counterclockwise, similarly to the above, for the left side plate body 32, the upper side of the air outlet 321 is the first side, and the lower side of the air outlet 321 is the second side. For the right side plate body 32, the lower side of the air outlet 321 is the first side, and the upper side of the air outlet 321 is the second side.

[0054] The cooking device 1 may only include one air outlet blade, and the air outlet cover 30 is provided with one air return opening 311. The air outlet blade is correspondingly arranged with the air return opening 311. Side plate bodies 32 are respectively arranged on both sides in the first reference direction, and air outlets 321 are formed on the side plate bodies 32. In this case, both sides of one air outlet blade are correspondingly arranged with one side plate body 32 respectively. Since the tangential directions on both sides of one air outlet blade are opposite, the flow guide plate 322 on one side plate body 32 is arranged on one side above in the width direction of the air outlet 321, and the flow guide plate 322 on the other side plate body 32 is arranged on the other side below in the width direction of the air outlet 321. Optionally, above may refer to one side in the second reference direction, and below may refer to the other side in the second reference direction.

[0055] Combined with Figure 4, the cooking device 1 may include two air outlet vanes. The main board body 31 includes two air return openings 311, and the two air outlet vanes are correspondingly arranged with the two air return openings 311. Side board bodies 32 are respectively arranged on both sides in the first reference direction, and air outlet openings 321 are formed on the side board bodies 32. In this case, the rotation directions of the two air outlet vanes can be selected to be opposite (one counterclockwise and the other clockwise). In this way, the tangential directions of the air outlet vanes close to the side board bodies 32 on both sides are the same, and the flow guide plates 322 on the two side board bodies 32 are both arranged on the same side (either on the upper side or on the lower side) in the width direction of the air outlet opening 321.

[0056] Combined with Figure 6 , the rotation directions of the two air outlet vanes can also be selected to be the same (both clockwise or both counterclockwise). In this way, the tangential directions on both sides of the air outlet vanes close to the side board body 32 are opposite. Therefore, the flow guide plate 322 on one of the side board bodies 32 is arranged on one side above in the width direction of the air outlet opening 321, while the flow guide plate 322 on the other side board body 32 is arranged on the other side below in the width direction of the air outlet opening 321.

[0057] In some embodiments, combined with Figures 9 to 11 , flow guide plates 322 are arranged on both sides in the width direction of the air outlet opening 321.

[0058] In some embodiments, an auxiliary board body 33 is arranged on at least one side in the second reference direction, and an auxiliary air outlet 331 is formed on the auxiliary board body 33. The auxiliary air outlet 331 can discharge a part of the air flow generated by the air outlet vanes into the cooking cavity 101. Since the auxiliary board body 33 and the side board body 32 are in different directions, the air flow generated by the air outlet vanes can be fully utilized in the above manner. By setting the area of the auxiliary air outlet 331 to be smaller than the area of the air outlet opening 321, the air pressure at the air outlet opening 321 can be increased, so that most of the air flow exits from the air outlet opening 321, which is beneficial to increasing the uniformity of the air flow through the arrangement of the side board body 32.

[0059] The above are only embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
